根分区重置xfs文件系统添加ftype属性

Boot into CentOS-7-x86_64-LiveGNOME-1804.iso.
Open a terminal and sudo -s.
Scan for LVM volumes: vgscan
Change into the appropriate volume group (centos in my case): vgchange -ay centos
Scan for the logical volumes in that group: lvscan
Create a mount point for the root FS: mkdir /mnt/root
Mount the logical volume corresponding to the root FS: mount /dev/centos/root /mnt/root
Dump to remote host: xfsdump -J - /mnt/root | ssh <host> 'cat >/data/rootfs.dump'
Unmount the root FS: umount /mnt/root
Recreate the root FS: mkfs.xfs -f -n ftype=1 /dev/centos/root
Mount the recreated root FS: mount /dev/centos/root /mnt/root
Restore from remote host: ssh <host> 'cat /data/rootfs.dump' | xfsrestore -J - /mnt/root
Reboot. Everything should be as it was before, except xfs_info / should now show ftype=1.
